My invention relates to improvements in pile eid-ting deviees for use in looms:` for weaving pile fabrics wherein the pile is i'ormed of floats oi weft threads over pile wires which extend in the direelvion of' the Werp.

When it is desired to enit lthe pile of 'fabric Woven on loomsl oi' this character, cutting de 'vices ere employed whiehnre connected to and form eonbinuzitione of the pile wires sind to which The pile is fed :is rapidly es elle fabrio is produced by the iooni.

The object of my invent-ion is te provide e pile cutting device of novel, simple und eii eient Construction adapted to be connect-ed to :i pile wire and to receive the pile therefrom end ent ii, :is the fabric is advanced by the loom.; :ind in whieli. o support provided with zi pile receiving port is employed in eombiniiion with o, pivoted knife :ind mow able ineens on the support, connected to the knife end ediipi'aed to be operated by ineelniw Diem of ehe looin to eetimre the knife relzif tively to its :support to eii'eet glie cutting; opel-:dion by eeneii'in the cutting edge of 'llie i knife to sweep Heroes the pile es ii, is ed winced along the piie receiving' perk of the sonneri. n

The body poriaion eonsiiii'nides the support for the other eleineide of the device und it is preferably inode oi? sheet metal bent to forni zi downwardly facing iop groove i and zin upwardly facing boioni groove (i connected :it one eide of the device by a side woll i'. Projecting' rezirvnrdly from one end of the bottoni olf ille side wall i' is e slender' port 8, the rearward end of which ie adopted to be connected to i'lie forward end oi' e pile wire 9. The part Si forme, in. effect, e een-- tinlndion of the aile wire i), und ii', is adopted to receive the pi e il@ therefrom the fobrie l1 ie produced und advanced by the loom.

The member 720 hue :i relirinrdlil extending erin E22 provided i'ii'li :i liderar-lili' nrojeeiinig pin-22 extending through :i eiot 23 formed in a platelike knife 2l which is held nor mally in engagement with the pin 22 by and vbetween a head 25 thereon and the bodj)7 "of the arm 2l. The knife 2-1 is arranged between an extension26 of the side Wall 7 on one side of the groove 6 and an extension 27 on the opposite side wall of the groove 6. The knife 24: is pivote-ily mounted on a pin 28 which penetrates the knife 24 and the Wall extensions 26 and 27 on the respective sides thereof; and the knife 24C is provided with a sharp cutting edge 29 on a curved line concentric with the pivot pin 28. The cuttin edge 29 is adapted to Work above the pie-receiving; part 8 and to sweep into i. and from the groove G in the part 8 when the yso knife 24 is reciprocated on the pivot pin 28; and the knife 24 is adapted to be thus reciprocated by the member 20 when it is moved back and forth within the grooves 3 and and the pin 22 Working in the slot 23 and eecting the reciprocations of the knife 24, when the member 2O is reciprocated.

The knife pivot pin 28 is carried by the free end of a spring arm 30 which extends from the vinside of the Wall 7 and which is securedthcreto by rivets 3l. rlChe arm 30 normally holds the pin 28 projected through the Walls 26 land27 and the knife 24:; and when it is desired to remove the knife 24C from the device, the arm 30 may be sprung outwardly to Withdraw the pin 28 from the knife 2li to permit its removal. After the pin 28 has been withdrawn from the knife 24 it may be readily removed from between the Walls 26 and 27 and Withdrawn from the pin' 22 for sharpening' or other` purposes. The member 20 is out out, at 32, to receive one end of the spring arm 30 in the same pla-ne therewith and to permit the re ciprocations ofthe member 20 Without interference with the arm 30.

Thev forward end of the member 20 eX- tends beyond the YWall 7 and has a notch' 33 cut therein to receive a rib 34 on the bar 35 which is secured to a bar 36. The bars 35 and 36 'and rib 8?: extend parallel to the breast beam 16 vandthe ends of the bar 36 are supported by rollers 87 which resi; upon brackets 38 projecting fixedly from the ends of the Ibreast beam 16. The 'bars 35 and 3G are adapted to be moved toward and from the breast beam 16 by suitable mechanism of the loom to eect the back and forth movements ofthemenrber 20 for the reciprocation or actuation of the knife 2s.

Aplurallty of the cutting' devices hereini 'beforeI described are adapted to be em les ployed on a. loom, the number employed corresponding with the number of rows of pile A floats to becut. The 'devices are arranged side by side on the bars lll and held in place by' the clamping bar i8, each device being connected to a pile Wire. 9 of the loom; andv Lsoacac v sides thereof and moves with the fabric 1l4 across the forward face of the breast beam 16 to the usual take-up roller as rapidly as the fabric is produced.

I claim l. A pile cutting devi comprising in combination a support hav-ing oppositely disposed grooves, an arm .fixedly mounted in said support, a knife pivotally mounted on said arm, a member slidably movable 1n the grooves of said support, connecting actuating means between said slidable member and said knife adapted to rock the knife on its pivotal bearingto effect the cutting operation, and means formino; part of said support yadapted to direct the pile to the cutting edge of the knife. g

A2. lin a pile fabric cutting device, the combination of a support having ,grooves therein, a knife pivoted on the support, and a. member slidably fitted to the grooves of the support and connected to and operative to 'actuate the knife to effect the cutting operation, the support having a, partadapted to receive the pile and direct 1t to the cutting edge of the knife.

3. In a pile fabric cutting,` device, the combination of a support, a, knife, and a spring arm carried by the support and having a pivot pin penetrating the knife and pivotally supporting the same, said arm being movable relatively to the knife to Withdraw the pivot pin therefrom, the support having a part adapted to r'eceive the pile and direct it to the cutting edge of the knife, the said knife being movable on its pivot to effect the cutting operation.

-4. In a pile fabric cutting device, the combination of 'a support, a knife pivoted thereon and having a slot therein, a spring arm carried by the support and having a pivot pin penetrating the knife and pivotally snpportmg the same, ysaid arm being movable relatively to the knife to Withdraw the pivot pintherefroni, and a. member movable on the support and having a pin projecting; into said slot and operative to actuate the knife to effect the cutting operation, the suppe/1,1,

bination of a support, a knife, and a spring arm carried by the support n ndfhavmg :i pivot pin penetrating the knife and e part of the support and pivotally supporting the 5 knife, said arm being movabieirelatively to the knife to withdraw "the pivot pin therefrom, the vsupport having a `part adapted to receive the pile and direct it to .the entf tingr edge of the knife, the seid knife being movable on its pivot to effect the cuting operation.

In testimony whereof, I affix my Signetnre hereto.
